In turbochargers a turbine is directly connected to a compressor. The power harvested by the turbine is used to power the compressor. In the figure below a turbine runs on steam and powers a compressor on air. Air can be considered a perfect gas with k = 1.34, R = 0.28 kJ/kgK and cp = 1.02 kJ/kgK. The air enters the compressor at pl = 1bar, T1 = 300K and a mass flow rate of mdot = 4.3 kg/s and exits at p2 = 4.3 bars. The steam enters the isentropic turbine at p3 = 2 MPa, T3=3200C and exits at p4 = 100 kPa. State 2 Isentropic Compressor State 1 Air - perfect gas T₁ = 300K P₁= 1 bar W = ? tubine State 4 Isentropic Turbine State 3 Steam T₁=320°C P3= 2MPa
What is the entropy at state 3? Answers in kJ/kgK What is the quality of steam leaving the turbine? What is the enthalpy at state 4? Answer in kJ/kg What is the power produced by the turbine? Answers in kW. What is the mass flow rate of steam through the turbine? Answer in kg/s
